摘要：
A method of forming a three-dimensional feature on a surface using the technique of drop ejection to deposit droplets of deposition material. The method comprises depositing a plurality of droplets on the surface to form a feature comprising multiple discrete portions, adjoining portions being formed from different deposition material. Examples of such a feature include a Braille character and a multi-layer optical device.
